Who is the man that survived 3 days underwater?
Harrison Okene survived for three days, without food or water, after his tugboat capsized off the coast of Nigeria six months ago. Now, video has surfaced of his dramatic underwater rescue at sea. The video shows how he was able to breathe, nearly 100 feet under the surface, thanks to an air pocket in the wreckage.
How do you create an air pocket underwater?
Doors can still provide an air pocket when open. If you’re trying to create an underwater structure, section the area with dirt/sand/gravel then repeatedly fill and empty areas with sand, dirt or gravel (or use sponges if available.
How long can you survive under water in an air pocket?
If the pressurized air pocket were about 216 cubic feet (6 cubic m), Umansky reckoned, it would contain enough oxygen to keep Okene alive for about two-and-a-half days, or 60 hours. But there is an additional danger: carbon dioxide (CO2), which is lethal to humans at concentrations of about 5 percent.
Can you breathe underwater?
Humans cannot breathe underwater because our lungs do not have enough surface area to absorb enough oxygen from water, and the lining in our lungs is adapted to handle air rather than water. However, there have been experiments with humans breathing other liquids, like fluorocarbons.
How long can you survive in an air pocket?
“At 70,000 parts per million, you lose consciousness pretty rapidly,” Eric Hexdall, a nurse and clinical director of diving medicine at the Duke University, told National Geographic. Hexdall calculated that, in an air pocket the size of a U-Haul moving van, it would take about 79 hours before you lost consciousness.
